You just need to have a Pokemon with Ability Compound Eyes to lead the party, then switch into another Pokemon with Ability Frisk when you found the desired Pokemon to check if it holds the item you need.

Anyway, other than Nincada, you can also catch a Caterpie in Gale Forest and evolve it all the way. It evolves into Metapod at Lv. 7 and once again into Butterfree at Lv. 10, which will have Compound Eyes. Do not catch Wild Metapod or it will struggle in battles before it can evolve.
